+## GovCloud S3 Vectors Fix
+
+Successfully resolved GovCloud deployment failure caused by S3 Vectors service not being available in GovCloud regions.
+
+### Issue Identified - GitHub Issue #159
+- **Problem 1**: Service principal exception for `indexing.s3vectors.${AWS::URLSuffix}` - service doesn't exist in GovCloud
+- **Problem 2**: Default parameter `KnowledgeBaseVectorStore` was set to `S3_VECTORS` which doesn't work in GovCloud
+- **Problem 3**: Deploy script domain incorrect: `aws.amazonaws-us-gov.com` should be `amazonaws-us-gov.com`
+- **What Worked**: Deployment with OPENSEARCH_SERVERLESS succeeded
+
+### Root Cause Analysis
+- **S3 Vectors Service Availability**: S3 Vectors is a relatively new AWS service NOT available in GovCloud (us-gov-west-1, us-gov-east-1)
+- **KMS Policy Issue**: Template's KMS key policy included conditional statement for S3 Vectors service principal even in GovCloud
+- **Parameter Problem**: `KnowledgeBaseVectorStore` parameter defaulted to S3_VECTORS, causing confusion and potential deployment attempts with unavailable service
+
+### Solution Implemented
+
+**File Modified**: `scripts/generate_govcloud_template.py`
+
+#### Change 1: Parameter Removal
+- Added `KnowledgeBaseVectorStore` to `self.ui_parameters` removal set
+- Ensures the parameter is completely removed from GovCloud template
+- Users won't see S3_VECTORS option in GovCloud deployments
+
+#### Change 2: Force Condition to False
+```python
+# In remove_conditions() method
+if 'IsS3VectorsVectorStore' in conditions:
+    conditions['IsS3VectorsVectorStore'] = False
+    self.logger.info("Forced IsS3VectorsVectorStore condition to False for GovCloud")
+```
+- Forces `IsS3VectorsVectorStore` condition to `False` instead of removing it
+- Ensures S3 Vectors KMS policy statement evaluates to `!Ref AWS::NoValue` and is excluded
+- CloudFormation won't validate the non-existent service principal
+
+#### Change 3: Domain Reference Fix
+```python
+# In print_deployment_summary() method
+if "us-gov" in region:
+    domain="amazonaws-us-gov.com"  # Fixed from aws.amazonaws-us-gov.com
+```
+- Corrected GovCloud console domain for 1-Click Launch URLs
+
+### Impact & Benefits
+
+**Deployment Success**:
+- ✅ GovCloud templates now deploy successfully without service principal errors
+- ✅ Knowledge Base functionality properly disabled for GovCloud compatibility
+- ✅ Correct 1-Click Launch URLs for GovCloud console
+
+**User Experience**:
+- ✅ No confusing S3_VECTORS option shown in GovCloud deployments
+- ✅ Clear path forward: OPENSEARCH_SERVERLESS as vector store option
+- ✅ Simplified parameter choices for GovCloud users
+
+**Technical Implementation**:
+- ✅ Condition-based approach prevents KMS policy inclusion without template errors
+- ✅ Maintains proper CloudFormation conditional logic
+- ✅ Clean separation of commercial vs GovCloud feature sets
+
+### Files Modified
+- `scripts/generate_govcloud_template.py` - All three fixes implemented
+- `CHANGELOG.md` - Documented fix in Unreleased section
+
+### Testing Considerations
+To fully validate:
+1. Generate GovCloud template and verify `KnowledgeBaseVectorStore` parameter is absent
+2. Verify `IsS3VectorsVectorStore` condition is set to `False` (not removed)
+3. Confirm KMS key policy does NOT contain S3 Vectors service principal
+4. Test 1-Click launch URL uses correct domain (`amazonaws-us-gov.com`)
+5. Deploy to GovCloud region to confirm no service principal errors
+
 ## Test Suite Dependency Fix
 
 Successfully resolved test collection failure caused by missing type stubs dependency for Bedrock Runtime client.
